The most common reasons a 2015 Ford F-150 tire pressure warning light stays on are a leaking tire, a wheel that no longer holds air, or a faulty tire pressure monitoring system.
  • Tire Leaking Air: A puncture, valve stem issue, or rim damage can cause a tire to leak air, leading to loss of pressure.
  • Wheel Leaking Air: A puncture or damage to the tire or rim can cause air to leak, resulting in a loss of tire pressure.
  • Tire Pressure Monitoring System: A malfunctioning tire pressure monitoring system can be caused by faulty sensors or a dead battery in the sensor units.
Proper diagnosis will determine the exact cause of your symptom, saving you money on unnecessary repairs. The diagnostic experts at RepairPal Certified shops have the right tools and experience to solve any symptom.

How much does it cost to fix a 2015 Ford F-150 tire pressure warning light stays on?

Common Repairs

The total repair cost will vary based on the condition of your vehicle and the number of repairs needed to fix your symptom. Proper diagnosis will save you money by finding the exact repairs needed to fix your car right the first time.

When a tire pressure monitoring sensor fails, the tire pressure monitoring system control module will recognize a loss in communication and turn on the warning lamp which indicates the failure. This is most often the case. However, the tire pressure monitoring sensor may also fail by reporting incorrect tire pressures. This could cause a flat tire to go unrecognized, or a properly inflated tire to signal a low or high tire pressure warning.

When a relearn is needed, for any reason, the TPMS warning light will illuminate, and many vehicles will display a message relating to the TPMS system being inoperative or loosing communication. It is important to keep a watchful eye on tire pressures when this system is having issues because there is no warning available for underinflation or overinflation of the tires.

Wheels offer very few symptoms, but these symptoms should never be ignored. Visible cracks on the wheels may appear, especially after hitting a large bump, Most often, this will also be accompanied by loss of air from the tire on that wheel. Also, vibration in the steering wheel is very common when the tire is out of balance, and improper wheel nuts or bolts can cause creaking and popping noises to develop. Again, there are very few symptoms, but they should not be ignored.

The only symptoms requiring diagnosis for the tire pressure monitoring system warning lamp is if the warning lamp has illuminated while the tires have correct air pressure, or if the air pressure for the tires is out of specification and the warning lamp is off. This is because the overwhelming majority of cases where the TPMS lamp illuminates is due to the change in ambient temperature.

What steps should I take to diagnose the tire pressure warning light issue on my 2015 Ford F-150?

To effectively diagnose the tire pressure warning light issue on your 2015 Ford F-150, begin with a thorough assessment of your tire pressure. Utilize a reliable tire pressure gauge to check each tire, ensuring they are inflated to the specifications outlined in your vehicle's manual. This initial step is crucial, as incorrect tire pressure is a common cause of warning lights. Next, conduct a visual inspection of all tires for any signs of damage, such as punctures or bulges, which could also trigger the warning. If the tires appear to be in good condition and properly inflated, consider resetting the tire pressure monitoring system (TPMS) as outlined in your manual, as it may simply need recalibration. Additionally, don’t overlook the spare tire; low pressure in this tire can also activate the warning light. If, after these steps, the warning light remains illuminated, it may be time to consult a professional mechanic for a more comprehensive diagnosis, as there could be underlying issues with the TPMS or other related systems. By following this diagnostic approach, you can systematically address the problem and ensure your vehicle's safety on the road.

What could be causing the tire pressure warning light to stay on in a 2015 Ford F-150?

When the tire pressure warning light stays on in a 2015 Ford F-150, it can indicate several common issues that are manageable for DIY enthusiasts. The first step is to check the tire pressure in all four tires, as low pressure is the most frequent cause of the warning light. Ensuring that each tire is inflated to the recommended levels can often resolve the problem. If the tire pressure is adequate, the next area to investigate is the tire pressure sensors; a malfunctioning sensor can keep the warning light illuminated. Additionally, the batteries in these sensors may be low or dead, which is a simple fix that involves replacing the batteries. It's also important to inspect the wiring and connections related to the tire pressure monitoring system, as any damage or loose connections can lead to persistent warning lights. If these steps do not resolve the issue, recalibrating the tire pressure monitoring system through the vehicle's onboard computer may be necessary. By methodically addressing these potential problems, you can effectively troubleshoot and resolve the tire pressure warning light issue in your Ford F-150, ensuring both safety and vehicle performance.

What immediate steps should be taken if the tire pressure warning light on a 2015 Ford F-150 remains illuminated?

When the tire pressure warning light on your 2015 Ford F-150 stays illuminated, it’s crucial to act quickly to prevent safety hazards and costly repairs. Start by checking the tire pressure across all four tires with a reliable gauge, ensuring they meet the recommended levels outlined in your vehicle's manual. If you find any tires are underinflated, inflate them to the correct pressure immediately, as this simple step can often resolve the warning light issue. Additionally, inspect your tires for any visible damage, such as punctures or bulges, which could compromise your safety on the road. If you’ve adjusted the tire pressure and the warning light remains on, consult your manual for instructions on resetting the tire pressure monitoring system, as some vehicles require this step to clear the alert. Ignoring the warning light can lead to decreased vehicle performance and increased risk of tire failure, so if the light persists after these actions, it’s advisable to seek professional assistance from a mechanic. Taking these steps not only ensures your safety but also helps maintain the integrity of your vehicle’s tire pressure monitoring system.
